The most important reason to use synthetic oil is the manufacturers warranty requirements. Step-8: Insert Retaining Ring Forward clutch gets a retaining ring for a secure union with the reverse-high direct clutch drum. In other words, the R servo is a no-brainer because racers have been using it for decades with great success. Torque converters must always receive 1 to 2 quarts for a good pump prime and quick lubrication on start-up. The governor has two valves that work hand in hand. At a glance, the huge C6 pan has a little dogleg at the vacuum modulator, which makes it easy to identify. We also support Corvette events, swap meets and local Corvette club shows all over the world.
The gasket has a tendency to compress, so one pass with the torque sometimes is not enough. Keep in mind what direction the pressure is coming from. Step-11: Install Pressure Plate Low-reverse clutch pressure plate goes in last, including the selective snapring, which is sized to set clutch clearances based on thickness. But what about your transmission fluid? Step-8: Inspect Forward Clutch Completed forward clutch looks like this at rest with no pressure applied left. After the new filter is in place, wipe the pan gasket surfaces, carefully removing the fluid residue.
If you have a build-up of debris around the fill plug, you may want to wash off the area before removing the fill plug. If it drains quicker, the vent is stopped up. Changing the oil and filter will take care of the acids. The C6, unlike the C4, uses an intermediate servo apply lever to help provide mechanical advantage to apply the intermediate band. Kickdown linkage is for wide-openthrottle operation. Prior to 1972, a screw-in throttle valve and gasket is used. The higher the servo-apply-lever ratio, the greater the apply force.
It will pump out the transmission fluid, and in the meantime, you can be pouring it back in with a long spout through where the dipstick is. For the first-year the C6 was a standalone unit, meaning the valve body was Dual-Range for that year only. Do not install the fill plug until the excess fluid stops flowing out. We use this transmission fluid exchange machine to remove the majority of fluid from the automatic transmission. When secure, there are 24 clutch-piston return springs to install. This is a critical safety item; so pay very close attention to detail here. .
On top of the heat the fluid has to deal with, it is forced through small orifices regulating fluid flow. Oil contamination and change intervals Oil contamination occurs, but you do have some control over it. Multi-grade petroleum oils start with thinner viscosity base stock then add viscosity improvers that will increase with heat. Because the reverse planet is held still, this causes the sun gear to be driven in the opposite direction as the input shaft. This requires thorough examination of the Ford Master Parts Catalog if you want to be absolutely certain of the intermediate servo pieces you need for your C6. Differentials also have to deal with extreme pressure concerning gear to gear contact.
Thanks, Bob You will need more than just 3 qts to truly change the fluid. Step-7: Use Grease For Pump Gasket Retention Apply a thin film of transmission lube for gasket retention prior to front pump installation. Without going any further into the innermost workings of the torque converter, suffice to say tremendous heat is generated as the impeller and turbine come up to speed. For special driving conditions on snow and ice, the small dot off detent starts you out in second gear, with upshift into final drive once you get going. Usually after about five oil changes, the seal is ready for replacement. This keeps the governor from going to work below this speed.
Heat is the enemy of confined driveline components. Careful placement of the lift arms or jack pads is required to prevent panel damage. You may have to pull the fill plug and check the color of the fluid currently in the transmission pan before ordering. It is also mated to the forward clutch. This prevents overfilling and foaming of the fresh fluid.
Remember: the C5 would be much tougher on the fluids in race situations without an external cooler. Make sure struts are firmly seated refer to step 13 on page 110. We have not tried to sway you towards any particular brand of lubricant. As power flows to the sun gear, it travels to the low-reverse or rear planet carrier to the low-reverse ring gear, which is splined to the output shaft. After a few days, we noticed a slight knock at start-up.
This means you are faced with choosing between at least four basic types of C6 bellhousing patterns. The tranny was rebuilt in 1987 and has about 20,000 miles on it since. Cast aluminum pans offer fluid capacity and cooling capacity. Cold transmission fluid gives you an erroneous pressure reading on the high side because the fluid is denser when cold. It makes you wonder if those early low temperature engines were better off.
The same goes with transmissions; we take them for granted. C5-C6 Transmission and Differential Servicing C5 and C6 Corvette transmission placement is a radical departure from the traditional engine to transmission coupling. Anybody else ever heard of this, or tried it? There is no gasket or seal, only perfectly machined surfaces. Step-6: Install Low-Friction Torrington Bearings Performance Tip One path to a better C6 is to install low-friction Torrington bearings between geartrain stages. Looked and found signs of contact of tire to body or frame. Allow the car to run for around 15 minutes, and it should be up to full temperature. Torrington bearings handle friction better than those old thrust washers.
